Hi Kasturi - Thanks for feedback
> If cockpit+gdeploy plugin would be have been used then that would have automatically detected glusterfs replica 3 volume created during Hosted Engine deployment and this question would not have been asked Actually, doing hosted-engine --deploy it too also auto detects glusterfs. I know glusterfs fuse client has the ability to failover between all nodes in cluster, but I am still curious given the fact that I see in ovirt config node1:/engine (being node1 I set it to in hosted-engine --deploy). So my concern was to ensure and find out exactly how engine works when one node goes away and the fuse client moves over to the other node in the gluster cluster But you did somewhat answer my question, the answer seems to be no (as default) and I will have to use hosted-engine.conf and change the parameter as you list So I need to do something manual to create HA for engine on gluster? Yes? Thanks so much!
